DE2337783A1 - Concrete building slab component with service passages - with troughed inset floor recess with closable hole through to ceiling - Google Patents

Abstract

The prefabricated slab unit, with passage outlets for service leads or ducts, is for incorporation in walls or esp. ceilings, providing service connections from storey to storey. The trough-shaped recess is near the edge, set back from the floor surface, and the passage aperture extending through to the ceiling surface can be closed by a sealing unit which contains the outlet points for the services; this unit may form a lost guide template for rigid pipes, and may be held by protruding ties at the edge of the aperture. It may be grouted in the recess with concrete or hard-Setting plastic.

Plate-shaped component

The invention relates to a plate-shaped component, in particular made of concrete, with a lower ceiling and a upper floor area as well as with passage points for supply lines.

Bs is known for an efficient construction of buildings to use prefabricated plate-shaped components as wall and ceiling elements. Pur the passage of the supply lines The prefabricated ceiling panels must have passage points from one floor to the other.

It is known for example from German Offenlegungsschrift 2,130,492 to use in order to achieve passing stations formwork sf ass ons malice, the _r supply lines to the incorporation of versor or serve tubes in a desired position prior to the construction of the wall or of the floor. The known embodiment is an embodiment that fixes the position of the supply lines when pouring a blanket or the like. forms.

In order to achieve a positional fixation in prefabricated plate-shaped components, the invention is based on the initially introduced mentioned design and consists in the fact that an arranged in the area of the plate edge, set back from the bottom surface, trough-shaped recess is provided with a passage opening reaching up to the ceiling surface, which can be closed by a closure body containing the passage points for the supply lines. Of the Closure body can preferably be inserted into the passage opening from the bottom surface. He makes beneficial a lost guide for rigid installation pipes.

In a preferred embodiment of the invention, the closure body is provided with protruding holding parts on the edge the passage opening supported. This results in a hanging holder of the closure body. The breech body can in a particularly advantageous manner with his over a the part protruding from the plate surfaces form a screen for the supply lines.

Such an embodiment of the closure body as a diaphragm can in a particularly advantageous manner with an in the documents of the German utility model 7 237 302 cooperate described sanitary cell.

The recess, which has a trough-like training, can be intended to accommodate pipe sockets and drainage fittings, the mouths of which the bottom surface of the plate tower above.

In an advantageous embodiment of the invention are the closure body and the other line parts arranged in the recess by a potting compound in the recess. fixable. The casting compound can be made of concrete or also of liquid or paste-like, after Introducing solidifying plastic.

Further advantages and details of the plate-shaped component according to the invention are described with reference to the drawing. '.

The Pig. 1 shows a plate-shaped one in a perspective view Component according to the invention.

Fig. 2 shows a section I-I from Pig. 1 in schematic Depiction.

In Fig. 3 is a section II-II from Fig. 1 with supply lines and fittings shown schematically.

FIG. 4 shows a representation corresponding to FIG. 3

of a further embodiment according to the invention.

A plate-shaped component 1 is shown in FIGS shown schematically, which can consist of concrete. In the exemplary embodiment shown, the plate-shaped component 1 forms a prefabricated ceiling element with a lower one Ceiling surface 2 and an upper floor surface 3. In the area of the plate edge 4 is a set back from the floor surface 3, trough-shaped recess 5 is arranged, the one Passage opening 6 has. The passage opening 6 extends through to the ceiling surface 2 and is through a passage points 7, 8 closable for closure body 9 containing supply lines, not shown further. Of the Closure body 9 forms a lost guide for in particular rigid installation pipes. The closure body 9 borders together with the plate-shaped Component 1 to a vertically oriented Y / and element 10.

The closure body 9 is provided with projecting holding parts 11 held hanging in the passage opening 6. He is from hung up in the passage opening 6, the edge parts of the trough-like recess 5 abutment for the Form holding parts. The closure body 9 protrudes in the illustrated suspended position beyond the ceiling surface 2 and forms a panel 12 for with the protruding parts the supply lines. '"..

The recess 5 serves, as can be seen particularly well from FIG. 3, to accommodate pipe sockets 13, 14 and drainage · fittings 15 of the supply lines 16,17, their mouths the bottom surface 3 of the plate 1 protrude. The closure body 9 and the other line parts arranged in the recess 5 13, 14, 15 are fixed in the recess 5 by a casting compound 18, e.g. concrete. After completing the A floor covering 19, in particular a screed, can be applied to the floor surface 3 of the recess 5 with the casting compound 18 will. ·.

The one in Pig. 2, the closure body 9 is assigned a U-shaped shell 20, which covers the installed supply lines and is part of the documentation of the German Utility model 7 237 302 described sanitary cell can be. Otherwise, the same parts are given the same reference numerals Mistake.

The one in Pig. 4 is the passage opening 6 with a wedge-shaped edge contour 21 provided, which is intended to be in contact with a corresponding wedge-shaped leading edge 22 of the closure body 9. on In this way the protruding retaining parts 11 are unnecessary for the closure body 9.
